Milk and cream cooler



May ,6, 1930. J. N. REINERT MILK AND CREAM COOLER Filed July 6, 1928 Patented May 6 1930 P NT-brace JOHN N. REINERT, or BIRD'I'SLAN'D, MINNESOTA" MILK AND CREAM. coonnn v Application filed July-6, 192s. Serial No. 290,856. g

This invention relates to a milk or cream heatlng or-cooling device and has for its pri- 7 mary b ect to provide, in a manner as here'- inafter set forth, an improved apparatus of this character which is of simple construction and so designed that it may be readilydisassembledfor cleaning. 7

Another and important object therefore is to provide a cream or milk cooler or heater which can be kept .in a sanitary condition with a minimum amount of labor.

A still further object of the invention is to provide a cream or milk heating or cooling structure having few'parts and constructed in a manner which will permit of its being constructed economically. v

Further objects and advantages of this invention will be apparent as the description of the same proceeds and the invention will be 2 best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawings but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed inthe appended claim.

In the drawings Figure 1 is a longitudinal sectional viewthrough the milk treating structure;

Figure 2 is a top plan view of the structure with the cover thereof removed; I

Figure 3 is an end elevational view of the structure.

As shown in the drawing, the present cooler comprises a main casing body 1 having the tively and a removable top or cover 5, the cover being provided with a surrounding depending flange 6 which engages around the outerfaces of the side and end walls to maintain the receptacle tightly closed. s The receptacle 1 is preferably of vertically elongated rectangular cross sectional design as shown in Figure 3, and has extending longitudinally therethrough a series of pipes 7 which are arranged in two groups posiside, end and bottom walls 2, 3 and 4 respectioned side by side, the pipes of one group being arranged in a slightly higher plane 1 than those in the adjacent group. "In addition to the arrangementidescribed, each pipe of each group is arranged at an inclination, eachof the pip'esof one group inclined oppositely to the associate pipe of-the other group. Each of the pipe sections 7 extends at its ends through an end wall of the casing and exteriorly of the casing the ends of the pipes ofone group are connected to the adjacent ends-of the pipes of the other group by the return bends 8 which are detaohably connectedtherewith. T I

It will bereadilyseen from this that liquid" introduced 'into' the, funnel "9 whi'ch'is is also provided at each end with a handle member 12 anda handle 13 is also secured to e the, top or cover 5.

. In the use of the present structure,'if it is desired to "cool milk or cream as the same flows from a separator or under any other cond1t1ons, the receptaclev 1 1s filled with water cooled to the proper temperature and warm milk is poured into the detachable funnel 9 and allowed to flow 'ba'ckand forth through i the .cool water in the receptacle, through the pipes-7, finally discharging from theoutlet nozzle 10. j

While the description of the present structure has been confined totwo groups of pipes 7 it is, of course,;to be understood that I do not wish to limit myself to thespecific details for it is obvious that any. number of groups of'pipes may be employed. V

In order to further facilitate the disas- "sembling of the present-structure, each of the returnbends has one end enlarged as inclicated at 14, while the projecting end of the pipe 7 into which the other end discharges is similarly enlarged to receive the said other end of the return bend. With this'construction, each of the return bends may be quickly removed so that a cleaning brush may be in- 6 troduced into the pipes 7 and after cleaning the bends, may be as quickly returned to position. v

The same methodis employed for coupling the funnel and the discharge nozzle with their 10 respective pipes so that these elements may be easily and quickly removed and replaced.

From the foregoing description, it. will be I readily seen that While the present device may be used 'on a large scale in dairies for milk cooling, it may also be made smaller for use in thedhome and may, therefore, be universally use 1 WVhile the present structure'has been dey scribed as'an apparatus for heating or cool ing milk by the introduction of liquid into the receptacle 1 such as hot Water,it is, of course, obvious that steam or hot or cold air may be introduced into the receptacle in the place of: hot Water. 1 v I r Having described my invention, What I claim is z- A milk cooling device of the character described, comprising a receptacle,a plurality of tubes extending through said receptacle between and through opposite Walls and arranged in vertically spaced relation and further being inclined in the receptacle, a plurality of tubes arrangedat one side of the first mentionedtubes and arranged invertically spaced relation in and extending at their ends through said opposite Walls and inclined oppositely to the first mentioned tubes, the upper one of said first mentionedtubes having its highest end turned to extend vertically 40 ex'teriorlyof the receptacle, means connected with said upturned end to facilitate introduction of liquid to the tube, return vbends connecting the ends of the first mentioned tubeswith the adjacent ends of the second mentioned tubes, said bends having frictional slip connection with the tubes, and a lead-off tube connected to the lower end of the lowest. one of the last mentioned tubes. r

In testimony whereof I hereunto afiix my signature. r
